Hello, we are getting a very similar behaviour. I wondered as it's winter he's getting earlier and fed earlier. . We take him out at 11 and he is pooping but cries about 3.30 and does need a poo - it's definitely I want to go out for the loo cry rather than a give me attention cry. I did read somewhere else about feeding later so we might give that a shot, I'd be interested in Mrs C's results!
